Griend is a bird watch island in the middle of the ‘Waddenzee’, about 20km off-shore. Mostly two researchers are permanently present on the island to monitor and control different bird types during the seasons. Data of the bird population is transferred into locally installed computers to analyze directly on spot. To assure enough energy production for the computers with attached hardware as well as the accommodation, we installed an off-grid PV system.
The solar panels have been mounted on a sloped roof, which is on the right angle for maximum energy output. Via 12V controllers the maintenance free gel batteries are charged in four steps to optimize battery life. Pure sine wave inverters assure the researchers working on the island to have enough power needed for their computers, research equipment and basic energy consumption. The installation of the house itself including the heavy batteries has been done onshore, before shipment to the island by boat. Further installation has been performed on the island after the house was placed on site.
